Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from clouds to the Earth's surface.

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to rivers, lakes, and oceans.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air through small openings in their leaves.

Front

How does the sun affect the water cycle?

Back

The sun provides the energy needed for evaporation and transpiration, driving the water cycle.

Front

What is the role of clouds in the water cycle?

Back

Clouds form during condensation and are essential for precipitation, as they hold water vapor that eventually falls as rain or snow.

Front

Where does evaporation occur most rapidly?

Back

Evaporation occurs most rapidly over oceans and large bodies of water due to the abundant heat and surface area.

What happens to the water cycle in a desert?

Back

In a desert, the rate of evaporation is high, but there is little precipitation, leading to a dry environment.
